The current implementation is to create two devices for MythTV - one for each tuner. The two devices don't interact with each other so there is no need to cross-link in software. This approach also allows you to use one tuner for a MythTV box and the other for something else. > Can they issue DiSEqC commands? > No. > -- Daniel > > _______________________________________________ > mythtv-dev mailing list > [email protected] > http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev > > _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
